ROLLS FOR ROLLING TOERAILS.

SPECIFICATION forming part of Letters Patent No. 335,268, dated February2, 1886.

.Application filed September 28, 1885. Serial No. 178,340. (No model.)

To all whom it may concern,.-

Be it known that I, SAMUEL E. BROWN, a citizen of the United States,residing at Cleveland, county of Cuyahoga, and State of Ohio,

have invented certain new and useful Improvements in Rolls for RollingToe-Rails; and I do hereby declare the following to be a description ofthe same, and of the manner of constructing and using the invention insuch full, clear, concise, and exact terms as to enable any personskilled in the art to which it appertains to construct and use the same,reference beinghad to the accompanying drawings, forming a part of thisspecification, the principle of the invention being herein explained andthe best mode in which I have contemplated applying that principle so asto distinguish it from other inventions.

The object of my invention is to provide a 2o toe-rail for carriages asthe product of a rolling process through a roll-pass. Such rails arecommonly cast or forged, and not made by the agency of rolls.

My invention consists of a set of rolls for the making of said rails.

Figure l is an end elevation showing the rolls in cross-section. Fig. 2is a similar view of rolls, somewhat different in construetion,of theshape of groove from the former. Fig. 8

3o is a side view of a rail-blank after its issue from roll-pass of Fig.l. Fig. 4 is a side view of a rail-blank after its issue from roll-passof Fig. 2. Fig. 5 is a face view of a rail issued from roll-pass of Fig.l. Fig. 6 is a similar view of a rail issued from the roll-pass of Fig.2 after it has been additionally handled.

Fig. 7 is a detail view representing a portion of the lower roll-surfaceprovided with prick punches.

A in Fig. l is the lower roll having its working-face smooth, with theexception of the Small prick-punches a, formed on it. B, the companionroll, has on its working-face the circumferential groove b, with itsbottom concave, and so about half-spherical in contour, with theexception of portion b. Said portion b is of less width and greaterdepth than the remaining portion of the groove, so

that a passing rod will no longer at that point 5o forcibly impinge onroll A, as in the other portions of said groove.

C, Fig. 3, is a side view of a rail after it has issued from pass ofFig. 1, and shows its main body portion convex on one side and flat onits opposite side, and with its end portions, 5 5 c, substantiallyround. Fig. 5 is a face View of the same rail, showing the projectingspurs d formed by the prick-punches.

In Fig. 2 a portion, b', of groove b is shown l provided with theportion b2, extending not 6o quite to the peripheral surface-line ofroll B, and having its top b flat.

This modified form of my invention is adapted to flatten the parts ofthe rolling rod which form the extremities of the toc-rail, as saidrolled rod is suitably severed to form said rails. Portion b2 of theroll-groove is hence of less width and less depth than the main portionof said groove b.

Fig. 6 is a face view of a rail issued from 7o this modified form ofrolls, and forged to a desired shape for application to a vehicle. Saidrail is opposiiely convex and [lat in its main body portions c,substantially round at its ends c', and flat on both sides at the ex- 75tremities o of said round portions.

f is an additional strength cning-strap, forged onto said rail,preferably near its middle portion.

In practice a bar of iron is reduced or modi- So fied, in previousroll-passes not here shown, until it is at thc desired size and shape,the latter being substantially round for use in my invention. It is thenentered between rolls A and B, and issued in any preferred lengths,showing different shapes and forms in different portions of its extent.

It is to be understood that the portion b of groove b is o'f dimensionscorresponding substantially with the dimension of the rod as it 9o firstenters the pass, so that the dimensions of said rod are not reduced insaid portion.

Roll Amay have its prick-punches cformcd in any suitable design, so asto produce the desired pattern on the face of the toe-rail.

The combination, with roll B, grooved sub` stantially as set forth, ofroll A, provided with prick-punches a, substantially as set forth.

In testimony that I claim the foregoing to IOO be my invention I havehereunto set my hand this 19th day of September, A. D. 1885.

SAMUEL E. BROWN.
